Now, because handle 10H advances, so the temporary transient lock piece 10B of handle 10H is separated from the temporary transient locking pawl BK of the temporary transient lockup arm 11B that engaged with temporary transient lock piece 10B.Then, completely lock piece 10A as at Fig. 3 A and Fig. 3 C(3) as shown in engage with the complete locking pawl AK of complete lockup arm 11A.In above state, power terminal 10T1 is as at Fig. 3 C(1) as shown in form close contact with pairing side power terminal 20T1, and signal terminal 10T2 is as at Fig. 3 C(2) thereby as shown in extend in pairing side signal terminal 20T2 and be electrically connected on this pairing side signal terminal 20T2.
[on complete lock position, in non-joint completely, there is not the reason of arc discharge]
Therein as at Fig. 3 C(4) as shown in, completely lockup arm 11A and completely lock piece 10A on lock position completely in the situation in non-complete engagement state, because power terminal and signal terminal are respectively in connection status, so charging current flows in power terminal.When impact is applied to connector, lockup arm 11A and complete lock piece 10A may discharge from engaging because of non-complete engagement state completely.Thus, due to the active force of driving of wind spring 10S, handle 10H moves immediately backward, and just the lock piece 10B near complete lock piece 10A engages with temporary transient lockup arm 11B, thereby stops the motion backward of handle 10H so that it is in temporary transient lockup state.On temporary transient lock position, signal terminal 10T2 is disconnected, but thereby arc discharge does not still occur power terminal 10T1 in contact condition.Therefore, when the disconnection of signal terminal 10T2 detected in above state, and charging circuit is while stopping power terminal 10T1 to switch on, and safety removes or ressembles and can be carried out.With above contrary, because prior-art devices does not have this temporary transient lockup state, so when the reaction force due to lever meets accident disconnection, connector is suddenly disconnected mutually, and from the time cycle of the disconnection that is disconnected to power terminal of signal terminal be short, now may there is arc discharge thus.
[general introduction]
According to the present invention, even interfering between two connector shells during the assembly manipulation of connector and matching connector in the situation of wearing and tearing when lever is subject to grasping, lever is also stopped, thereby start charging under the occasion (non-complete engagement state) that lever is not upwards grasped on complete lock position therein, and after this, thereby apply to impact in above-mentioned occasion, connector is discharged from non-complete engagement state, handle moves backward and is locked in the temporary transient lock position of the most close complete lock position from complete lock position.On temporary transient lock position, signal terminal is disconnected, but thereby arc discharge does not still occur power terminal in contact condition.Thus, because disconnection and the charging circuit of signal terminal detected in above-mentioned occasion, stop power terminal energising, so safety removes or ressembles and can be carried out.Meanwhile, this embodiment has structure like this: wherein handle in shell backward or move forward, but the invention is not restricted to this.The present invention can be applied to wherein handle not in shell backward or the structure moving forward.In above-mentioned occasion, temporary transient lock piece and completely lock piece can be arranged on connector body.
The Japanese patent application No.2011-113931 of the application based on submitting on May 20th, 2011, its content is merged in by reference at this.
